Potential improvement:

In Section: Handling Events
http://localhost:3000/tutorial/handling-events

The first example creates a function that contains a button
"function ClickableButton(props){ ..."
The second example creates a function that contains an InputBox
but it still uses the name ClickableButton

Although this is not an error, using the second function name confused me since I thought the two examples were talking about the same thing until I cut and pasted them to do a quick comparison.
recommended solution: Changing the second name to function "ChangeableInput" would reduce the confusion.

BTW: excellent tutorial. thank you.
